Performance problem with rich panel menu in Internet Explorer
-------------------------------------------------------------

                 Key: RF-8620
                 URL: https://jira.jboss.org/jira/browse/RF-8620
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: performance
    Affects Versions: 3.3.3.Final, 3.3.2.GA
         Environment: Windows XP, IE7
Firefox 3.5.9
            Reporter: Marius Seiceanu


We have an application which shows a menu (rich:panelMenu mode="client") with 275 entries. Entries are structured on 4 levels using rich:panelMenuGroup and rich:panelMenuItem).

The problem is that loading of menu takes 6seconds in IE7 on a computer with 1.6GHz CPU. 
CPU is highly used during load of menu.
In FireFox load of menu takes less than 2sec.

Same tests on a different computer with 2.0 GHz CPU:
- IE8 - 3sec
- FF3.5.9 - 1.1sec
